The present invention provides an image processing system, which can reduce calculation time by alleviating a calculation load in assessing the occurrence of tampering of an image. For example, the image processing system of the present invention first identifies a type of a form of an image to be assessed in assessing the occurrence of tampering. Next, a characteristic amount of a certain region (flexible region) corresponding to the identified type of a form is extracted as a characteristic amount of the image to be assessed. Then, the extracted characteristic amount of image to be assessed and the characteristic amount extracted from a certain region in an original image are compared and the compared result is notified as the assessment result. A flexible region, to which a user writes, is preferably specified as said certain region.

Image processing system and image tampering assessment method and control program of the same

An apparatus being connectable to a printing apparatus and an information processing apparatus, comprising, a reception unit adapted to receive identification information used to identify the printing apparatus and used to specify a printer driver in the information processing apparatus, from the printing apparatus after connection to the printing apparatus, a storage unit adapted to store the identification information received by said reception unit, a transmission unit adapted to transmit the identification information stored in said storage unit to the information processing apparatus after connection to the information processing apparatus, a second reception unit adapted to receive print data generated in the information processing apparatus using a printer driver specified based on the identification information, from that information processing apparatus, and a second transmission unit adapted to transmit the print data received by said reception unit to the printing apparatus.

Print control apparatus connectable to a printing apparatus and information processing apparatus, and control method thereof, and computer program

An image processing method includes steps of acquiring information about image conditions, such as resolution settings, supported by a first print device for printing image data; generating an image data item corresponding to each acquired image condition; determining an image attribute, such as a character image or a dot image, included in each of the generated image data items; trimming an image in an area including the image attribute from each of the image data items; laying out the trimmed images on prepared template data; and printing out the template data using a second print device different from the first print device.
